Hi WikiNote, So basically a way to control on which pages (taking nested pages into account) attachments can be added and a way to control the # of attachments for a given page (taking nested pages into account). For the inventory idea, the only downside I can see is that you’d need to be careful not to have too many attachments on a single page since this could lead to memory issues when loading the page. Generally speaking this looks like a good idea and I’d suggest that you create a jira issue for tracking this idea. Right now the feature you ask doesn’t exist out of the box. But as with everything in XWiki, with a bit of coding it’s possible :) Technically speaking, this means modifying the UploadAction.java class and checking for config parameters in there. The nice thing (but not mandatory) would be to reimplement UploadAction which is coded using some old technology with a newer EnityResourceAction (see http://extensions.xwiki.org/xwiki/bin/view/Extension/Resource+API#HAddingan…).
